Title: Displacement monitoring
Inventor: FOTHERGILL IAN ROBERT
IPC: G01B11/16
Filed: 1988-08-11
Abstract: Displacement or strain is measured by applying to a body 10 to be monitored at least one grid line 12 (two or more where strain measurements are required) and scanning a radiation beam such as a laser beam across or partly across the grid line(s) 12 to produce a pulsed output from which the mean position(s) of the grid line(s) 12 can be ascertained with reference to a datum point on the beam scanning path. Displacement of each grid line 12 relative to the datum point can be determined. The beam scan may be adjustable to produce a null condition in which the mean position of the grid line(s) 12 coincides with the mid-point of the beam scan. Any deviation from the null condition then indicates displacement of the body 10 or strain thereof. Neutrons, X-rays or ultrasound could be used instead of light. <IMAGE>
